Fixed-Point Digital Signal Processor
SPRS139G–NOVEMBER 2000–REVISED JANUARY 2005
Table 5-34 and Table 5-35 assume testing over recommended operating conditions and P = 0.5 *
processor clock (see Figure 5-32 through Figure 5-34). In the following tables, DS refers to the logical OR
of HCS, HDS1, and HDS2, and HD refers to any of the HPI data bus pins (HD0, HD1, HD2, etc.). These
timings are shown assuming that HDS is the signal controlling the transfer. See the
TMS320C54x DSP
Reference Set,Volume 5: Enhanced Peripherals
(literature number SPRU302) for addition information.
